nco:ContactMedium

## nco:ContactMedium nco:ContactMedium |

## Description

A superclass for all contact media - ways to contact an entity represented by a Contact instance. Some of the subclasses of this class (the various kinds of telephone numbers and postal addresses) have been inspired by the values of the TYPE parameter of ADR and TEL properties defined in RFC 2426 sec. 3.2.1. and 3.3.1 respectively. Each value is represented by an appropriate subclass with two major exceptions TYPE=home and TYPE=work. They are to be expressed by the roles these contact media are attached to i.e. contact media with TYPE=home parameter are to be attached to the default role (nco:Contact or nco:PersonContact), whereas media with TYPE=work parameter should be attached to nco:Affiliation or nco:OrganizationContact.
